What is the method for odometer adjustment?
2 Answers
Odometer adjustment method is: 1. Unplug the odometer sensor connector under the car's hood; 2. Insert the output plug of the mileage adjuster into the sensor's signal socket; 3. Plug the mileage adjuster into the cigarette lighter; 4. Turn the car key to start the dashboard and adjust the control button on the mileage adjuster; 5. Adjust the vehicle speed accordingly. The odometer's function is to record the total kilometers traveled since the vehicle left the factory. Its working principle involves knowing the diameter of the car's wheels, calculating the circumference of the wheel to determine the number of rotations needed for one mile, automatically recording the wheel rotations, and dividing by the number of rotations corresponding to one mile to obtain the traveled distance.
Speaking of odometer tampering, I tried it myself when fixing cars before but stopped immediately. The methods are quite tricky: for old mechanical odometers, you have to dismantle the dashboard and manually turn the internal gears to adjust the numbers; for newer electronic ones, you need computer tools to rewrite the data through the OBD port. But this is just cheating—creating false readings to deceive people when buying or selling used cars. I later learned it's illegal, with hefty fines and even jail time as serious risks. If the odometer is genuinely broken, take it to an authorized dealership for proper repairs—they can recalibrate or replace the unit. Don’t cut corners for small gains; in the long run, protecting yourself and others is more worthwhile. Driving with a trustworthy, accurate mileage means fewer accidents and stable resale value. Always check the vehicle history report—issues often surface there. Bottom line: don’t DIY, leave it to the pros—safety first.
